John McCain’s rally on Friday once again inspired furious reactions from his supporters, with one woman screaming “traitor!” as McCain criticized Barack Obama’s tax record.

“traitor,” “bomb Obama!”

“He promised higher taxes on electricity,” McCain charged at the event in La Crosse, Wisconsin. “He voted for the Democratic budget resolution that promised to raise taxes on people making just $42,000 a year.” At that point, the woman yelled “traitor,” and both McCain and his wife Cindy appeared to look in her direction.

“mob-like”

As Talking Points Memo’s Greg Sargent noted, GOP loathing for Obama seems to also be “spilling into down-ticket races,” with one woman yelling “bomb Obama!” during a Thursday debate between Republican Sen. Saxby Chambliss and his Democratic challenger.

During a Friday appearance on Fox News, Obama aide Stephanie Cutter said that McCain’s crowds have become “mob-like” in their anger and argued that McCain cared “more about the state of his campaign than the economy.”

“The thing that is most important right now is that we have got to instill confidence in people in our economy. We have got to calm people down,” Cutter said. “We do not need to stoke fears on the campaign trail with these mob-like rallies that we have been seeing. We need to take a step back and provide steady leadership. This is a crisis. This is not what leaders do in crises. Barack Obama invoked FDR, ‘the only thing we have to fear is fear itself.’ Those are words to live by at this point.”
